Problem with powersteering, need help asap
I changed my powersteering tank over today, to a newly painted one.
I drained the fluid out, removed the old tank, put a new o-ring onto the pump, put new tank on.
then i refilled up with halfords powersteering fluid.
I started the engine, and did lock to lock turns, holding it fully left/right for a few seconds.
at this point i could hear the pump making a noise, like normal.
after a few more goes, the noise went away, but so did the powersteering.
I have dried some different fluid, but that hasnt helped.
the pump is moving the fluid around in the tank, and i removed the return pipe when the engine was running, and lots came out.
I have kepted a eye on the level, and it hasnt run dry.
any ideas?
thanks
ian

it was fine before, nothing wrong with it at all, apart form doing the turn to turn lock, is there anything else i can try? i am getting the fluid moving around in the tank, but i cant hear any noise from the pump, when on full lock.
it made a noise to start off with, but then after a few full locks each way, it stoped, and so did the power steering.

ok, i have been out this morning, jacked up the cardone it 40+ times tock to kock, then did it anain with the engine running.
and it still doesnt work
i didnt see any bubbles, but the fluid just went up and down.
it was up on full lock.
when on full lock with engine running, you dont hear any noise at all. and before when on full lock you could hear the pump working. (same as my friends classic impreza)
what can i try next?
or is there something buggered?

check if oil still returning to the reservoir if you have the wheels on full lock with some force on the steering wheel. This should close the valves in the rack and therefore triggering the max pressure valve in the pump. this should cause the normal return flow to stop.
if the returnflow doesn't stop -> the valves are buggered
If the returnflow does stop but no noise -> pomp can't make pressure thus pump buggered..

another up date, I have fitted another pas pump, that i brought from a scooby brakers, but now problems again.
the power steering was working, i went out for a drive (around 3-4 miles max) and it has stopted again. did the bleeding in like normal.
when the car is running, but parked, it doesnt work, rev the car up to around 3k reves, you can feel the pas coming back again.
any idea on what could be causing this?
i have just been using normal atf fluid (dextron i think)

YOu are definitely fully filled with fluid? Because when the reservoir looks full, you can actually keep putting loads more in for quite a while without it coming up any more. That cured a noisy PS system on mine, I hadn't filled it properly.

when i fitted it today, after bleeding bit, on full lock with engine running, i got the noise from the pump, but now on full lock, engine running, no noise at all.
the only difference is (car is parked) when i rev the engine up 3k+ the power steering starts to come back.
if anything the fluid is abit on the high side now

so some more up dates.
been out this morning, I have taken the pas lines off the steering rack, and fully bled the system.
refilled, and bleed it again.
started off pas was working, then it got harder, then stopted working again.
then if i reved the engine, the pas started to work.
when engine was up to working temp, the pas did not work at all, even when reved.
sounds like a dodgy pump again?
